Pokédex entries

What each game says about it, in the games' own words.

Red / Blue / LeafGreen / Y	Rarely seen in the wild. Huge and vicious, it is capable of destroying entire cities in a rage.
Yellow	Brutally vicious and enormously destructive. Known for totally destroying cities in ancient times.
Gold	They say that during past wars, GYARADOS would appear and leave blazing ruins in its wake.
Silver	Once it appears, it goes on a ram page. It remains enraged until it demolishes every thing around it.
Crystal	It appears when ever there is world conflict, burning down any place it travels through.
Ruby	When MAGIKARP evolves into GYARADOS, its brain cells undergo a structural transformation. It is said that this transformation is to blame for this POKéMON’s wildly violent nature.
Sapphire	Once GYARADOS goes on a rampage, its ferociously violent blood doesn’t calm until it has burned everything down. There are records of this POKéMON’s rampages lasting a whole month.
Emerald	It is an extremely vicious and violent POKéMON. When humans begin to fight, it will appear and burn everything to the ground with intensely hot flames.
FireRed	It has an extremely aggressive nature. The HYPER BEAM it shoots from its mouth totally incinerates all targets.
Diamond	Once it appears, its rage never settles until it has razed the fields and mountains around it.
Pearl	In ancient literature, there is a record of a GYARADOS that razed a village when violence flared.

Alpha Sapphire	Once Gyarados goes on a rampage, its ferociously violent blood doesn’t calm until it has burned everything down. There are records of this Pokémon’s rampages lasting a whole month.
Sun	A tale is told of a town that angered Gyarados. Before the sun rose the next day, flames utterly consumed the town, leaving not a trace behind.
Moon	There are people who swear that any place Gyarados appears is fated for destruction.
Ultra Sun	It fires hyper beams in all directions, burning the surrounding area to ash. There are some regions where it’s called “the deity of destruction.”
Ultra Moon	The energy from evolution stimulated its brain cells strongly, causing it to become very ferocious.

Official data here is present-day reference data from PokéAPI, not a snapshot of any one game's era — the Fairy type and hidden abilities arrived partway through the series, so a difference against an older game can belong to the series rather than to that ROM hack.
